Further, the same procedure is repeated to sequentially stack the second container C ₂ and the first container C ₁ .

As described above, the third container C ₃ in the central container storage 5b is lowered to the lowermost position by operating the elevating device 10, and the second container C ₃ in the rear container storage 5c is further lowered. _2, the traveling trolley 7 moves to the center container receiving portion 5b, by a subsequent similar procedure is laminated on the third container C _3. Finally, by moving the first container C ₁ in the center of the container housing portion 5b, by a subsequent similar procedure is laminated on the second container C _2. The procedure for loading and unloading the first and second containers C ₁ and C ₂ may be reversed.

According to such a procedure, three containers C ₁ , C ₂ and C ₃ can be stacked at a predetermined position in the container yard in a short time.

When only the third container C ₃ located at the bottom is required, the third container C ₃ is loaded on the transfer device 2 by the same procedure as for loading, and the shift device 3

Next, referring to FIG. 1 and FIG.
The method of moving to the container yards A to D will be described.

First, the transfer device 2 is moved to the shift device 3 at the right end of the device, and the transfer device 2 is mounted on the shift trolley 20 of the shift device 3.
It is moved in the direction of the arrow shown in FIG. The drive system of the shift trolley 20 is provided with a mechanism that locks the shift trolley 20 and the rails 1a of each row in alignment with each other, thereby moving the shift trolley 20 from row A to row C, for example. be able to. Since all the rails 1a have the same width, the loading and unloading of containers in the container yards A to D can be performed in the same procedure as described above. In this way, by providing the shift device 3 including the shift cart 20, the loading / unloading operation in each of the container yards A to D can be performed using one transfer device 2.

As described above, according to the present embodiment,
There is no need for a conventional passage for a lift vehicle between each row of containers, and substantially the entire space can be effectively used as a container yard.

Further, since the container transfer device 2 is installed above the frame 1, it is not necessary to construct a building for providing an overhead crane as described in Japanese Patent Laid-Open No. 4-59501. Only by installing the container hangar of the present embodiment, it is possible to use it in a field or the like.

Further, since the transfer device 2 for transferring containers is provided with the shift device 3 which can be transferred to a different row of container yards, one transfer device can be used in a wide yard at a low manufacturing cost. Work becomes possible.

In the above-described embodiment, the case where three layers of containers are stacked has been described. However, it is needless to say that the present invention is not limited to this, and can be applied to more layers. In this case, the transfer device 2 of the above-described embodiment can be used, but the container mounting space of the transfer device 2 can be increased according to the number of layers to be stacked. Further, in the present embodiment, the shift device 2 is provided at the end of the frame 1, but the position is not limited thereto, and may be provided at both ends of the frame 1.
Particularly when the frame 1 is long, the transfer device 2 can be operated quickly and efficiently by providing the frame 1 at the center of the frame 1.

FIG. 7 is an overall perspective view of a storage unit showing an example in which containers are stacked in five stages.

As in the example of FIG. 1, the frame 1 of the hangar is constituted by columns 1a and girder 1b which are high enough to stack five containers, and a total of five rails 1c are arranged on the upper surface of the girder 1b. ing. Further, a transfer device 21 that travels on the rail 1b is provided, and a shift device 22 that stacks and unloads containers and moves the transfer device 21 to each container yard is provided.

The transfer device 21 is different from the previous example in that
Container storage frame 23 running on the book rail 1c,
It is composed of a traveling frame 24 that moves the upper surface of the container housing frame 23 in the same direction as the traveling frame 24 and a transfer trolley 25 that moves the upper surface of the traveling frame 24 in a direction perpendicular to the moving direction of the container housing frame 23. Have been.

The container storage frame 23 has a capacity capable of mounting a total of six containers in three rows in the traveling direction and two rows in the width direction, and is provided with one of a plurality of wheels 23a provided at the lower end. The vehicle travels by being driven by an electric motor (not shown) or the like. In addition, two rails 23b parallel to the traveling direction are provided at the upper end of the container storage frame 23.

The traveling frame 24 is of a self-propelled type that travels on a rail 23b of the container storage frame 23 by electric motor driving, has a frame shape substantially equal in length to that of the container, and is orthogonal to the traveling direction. Is provided with two rails 24a on its upper surface.

The transfer trolley 25 is the rail 2 of the traveling frame 24.
Similarly, it is possible to run on 4a by driving an electric motor. An electric motor 25a for stacking and unloading containers is arranged on the upper surface of the transfer trolley 25, and a gripping device, a horizontal bar, a suspension arm, a locking claw similar to those shown in the examples of FIGS. And the like, the container can be handled similarly.

The shift device 22 is constructed by the columns 22a and the girder 22b, and has a capacity to arrange a total of ten containers in a plane. The upper surface of the girder 22b is provided with three rails 22c orthogonal to the traveling direction of the container storage frame 23, and a motor driven shift carriage 26 that moves on these rails is provided.

The shift carriage 26 has three rails 26a on its upper surface, and can be moved to the three rails 1c of the frame 1 by moving on the shift device 22, as shown in the figure.

In the above configuration, the loading and unloading of the containers by the transfer trolley 25 is performed in exactly the same manner by the same mechanism as in the previous example, and the handling of the containers to the trucks by the shift device 22 is also the same. is there.

In the illustrated example, the container storage frame 23 of the transfer device 21 is located on the frame 1 of the hangar,
And a total of 6 included in the range of the container storage frame 23 by combining the traveling directions of the transfer trolley 25 and the transfer trolley 25.
It is possible to load and unload containers on the yard by the transfer trolley 25 for individual containers.
The container storage frame 23 on which a maximum of six required containers are loaded uses the rail 26a of the shift trolley 26 which is aligned with the container storage frame 23 on the shift device 22 side and stands by. Shift device 2
Move up 2.

The container storage frame 23 placed on the shift trolley 26 unloads the containers loaded thereon using the transfer trolley 25. This operation is also performed in the same manner as in the previous example. In addition to the movement of the shift carriage 26, the movement of the traveling frame 24 and the transfer trolley 25 is combined to unload the container at any of the ten loading / unloading positions. be able to. Thereafter, the empty container storage frame 23 returns to the frame 1 side of the hangar, and carries out a similar container unloading operation.

When it is desired to set the container storage frame 23 on the right side differently from the position shown in the figure, when the container storage frame 23 is located on The carriage is moved rightward from the position shown in the figure, and the rail 26a is adjusted to the position of the rail 1c on the frame 1 side. When the container storage frame 23 is returned to the frame 1, the containers can be stacked and unloaded at different container yards.

Further, in the example of FIG. 7, since the container storage frame 6 has a capacity including a total of six containers, the containers located in the container yard in this range are moved by the traveling frame 24 and the transfer trolley 25. Can be performed only by synthesis of Therefore, even in the case of a four-row container yard, it is not necessary to frequently transfer the container storage frame 6 to the shift trolley 26 and return it to the frame 1 again, thereby improving work efficiency. . The same applies to the operation of stacking and unloading containers by the shift device 22.

As described above, by increasing the loading capacity of the container storage frame 23, it is possible to efficiently handle a plurality of containers. Therefore, not only can the area of the site be reduced by stacking in five layers, but also the efficiency of loading and unloading containers can be greatly improved.

[0057]

According to the present invention, the following effects can be obtained.

(1) Since the containers can be stacked from above by the transfer device provided on the frame, the work space required for the traveling of the lift truck, which is conventionally required, becomes unnecessary, and most of the site is used as a container stacking yard. It can be used effectively.

(2) Center, front, rear, etc.
By providing a plurality of container storage units, a plurality of containers can be transported in one movement cycle, and the work time can be reduced.

(3) For the same reason, it is easy to take out the stacked lower containers, and the efficiency of the cargo handling operation is improved.

(4) The container transfer device is configured to include a plurality of rows of a plurality of containers, and the handling of the container is enabled by synthesizing the movement of the traveling frame and the transfer trolley. Moving can be reduced, which not only reduces the site area of equipment, but also
The work efficiency of unloading is greatly improved.
